Short to ground in one of the light fixtures. replace the fuse with a test light. Test light will glow. remove bulbs and fixtures one at a time until light goes out that will determine which unit is bad --replace as necessary
I would check the switch inside the steering column.
because of the flashers relay in dash board.
hazards and turn signals have separate flashers. replace flasher for turn signals
You may want to check the thermal flasher.
Bad switch in steering column? diffrent fuses.
turn signals and emerg flashers work off a flasher can. go to any auto store and buy a new one they are cheap and easy to replace
The emergency flashers and the signal lights are separate systems. Each has it's own fuse, switch and flasher relay. If your turn signals light up but don't blink I would blame the signal flasher relay.
We need more information. Never work? Come on and not blink? Do the 4way flashers work?
The bulb is bad. Turn signals and flashers use different bulbs.
have you checked your fuses?
4 way flashers and turn signals both have a "flasher can" in the system to make the lights flash the turn signal and 4 way flashers are controlled independantly of each other try replacing the flasher can for the 4 way flashers it is obvious that the bulbs are ok because they work on turn signals
you probally have a bad wire that is shorting out and blowing your fuses.
